An optical system according to an embodiment of the present invention includes a first lens having positive (+) refractive power; a second lens; and a third lens having negative (-) refractive power, wherein the first to third lenses are sequentially arranged from an object side to an image side. The optical system includes an aperture disposed between the first lens and the second lens, and the refractive index of the first lens may be smaller than the refractive index of the second lens. Thus, the present invention can provide the optical system and camera module with improved optical characteristics.
